Shock formation around planets orbiting M-dwarf stars
A. A. Vidotto, J. Llama, M. Jardine +2
Bow shocks can be formed around planets due to their interaction with the coronal medium of the host stars. The net velocity of the particles impacting on the planet determines the…
The shocking transit of WASP-12b: Modelling the observed early ingress in the near ultraviolet
J. Llama, K. Wood, M. Jardine +4
Near ultraviolet observations of WASP-12b have revealed an early ingress compared to the optical transit lightcurve. This has been interpreted as due to the presence of a magnetosp…
Transit Variability in Bow Shock-Hosting Planets
A. A. Vidotto, M. Jardine, Ch. Helling
We investigate the formation of bow shocks around exoplanets as a result of the interaction of the planet with the coronal material of the host star, focusing on physical causes th…
Understanding the Angular Momentum Loss of Low-Mass Stars: The Case of V374 Peg
A. A. Vidotto, M. Jardine, M. Opher +2
Recently, surface magnetic field maps had been acquired for a small sample of active M dwarfs, showing that fully convective stars (spectral types ~M4 and later) host intense (~kG)…
